  1. 1. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Ellen Lundin; Lovisa Liljenberg; [2023]
    Keywords : LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

    Abstract : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. READ MORE

  3. 2. The Effects of Climate Change on Zirben (Pinus cembra) Distribution in the Italian Alps

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nicholas Asplin; [2023]
    Keywords : Pinus Cembra; Tree line; Tree line shift; Alps; Climate change; Earth and Environmental Sciences;

    Abstract : Anthropogenic climate change has caused temperature increases all across the globe. Mountainous areas are among the most affected and are experiencing alarming rates of warming. Such rapid warming will have effects on alpine vegetation and their distribution throughout the alps. READ MORE

  4. 3. Molecular Interactions Between Xanthan Gum, Psyllium, Milk Proteins and Starches, and Their Implications on Gluten-Free Bakery Products

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Carolin Bischoff; [2021]
    Keywords : Rheology; Xanthan gum; Gluten-Free; Food Technology; Technology and Engineering;

    Abstract : Gluten in bread can cause severe health problems in patients with celiac disease. However, gluten-free substitutions often show impaired quality characteristic like a liquid dough because of a missing gluten-network or accelerated staling due to the high amount of gluten-free starch.

  5. 4. Smoltification status of Atlantic salmon (Salmo salar) in relation to migratory success and migration speed in a regulated river

    University essay from Karlstads universitet

    Author : Johanna Högvall; [2020]
    Keywords : Atlantic salmon; juvenile downstream migration; parr-smolt transformation; regulated rivers; dams; migration delay; radio-telemetry; Atlantlax; vandringshinder; smoltifieringsgrad; reglerade älvar; radiotelemetri;

    Abstract : There is a concern that the ecosystems around the world are suffering from fragmentation. Ecosystems such as rivers have lost their connectivity to a large extent due to hydroelectric dams with no or insufficient passways for the natural flow of organisms, matter and energy. READ MORE

  6. 5. Generation and Characterization of Intense Attosecond Pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Marius Plach; [2020]
    Keywords : Attosecond physics; high-order harmonic generation; high harmonic generation; HHG; attosecond pulses; molecular dynamics; attosecond pulse generation; harmonic emission time delay; temporal reconstruction of attosecond pulses; strong field processes; Three-step model; RABBIT; Reconstruction of Attosecond Beating By Interference of Two-photon Transition; Terawatt Laser System; Intense XUV Beamline; XUV; LLC; Physics and Astronomy;

    Abstract : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. READ MORE
